in N
2
when calibration
the span point of your CO
2
sensor option (Table 3-12) is 20%.
9.7.2.2. SET CO2 SPAN GAS CONCENTRATION:
Set the expected CO
2
span gas concentration.
This should be equal to the percent concentration of the CO
2
span gas of the selected
reporting range (default factory setting = 12%).
